Added missing new permissions, and minor cleanup; switched Rel enum values back to previous values, for the sake of other plugins which might check against the actual enum value (for better compatibility with both 1.6.x and 1.7.x+ versions)

IMPORTANT NOTE:
Existing plugin users who are upgrading to this version will likely need to grant default permissions for recruits, like so:
f config factionPermDefaults door recruit
f config factionPermDefaults button recruit
f config factionPermDefaults lever recruit
f config factionPermDefaults build recruit
